Methods and systems for evaluating software for known vulnerabilities

ABSTRACT

A vulnerability identification and resolution (VIR) computer device for identifying security vulnerabilities in a computer system is provided. The VIR computer device includes a memory device for storing data including data representing computing assets installed in the computer system and a processor in communication with the memory device. The VIR computer device is programmed to receive an asset identifier identifying a computing asset selected for evaluation and execute a query on at least one database storing security vulnerabilities, the query searching for security vulnerability data associated with the selected computing asset. The VIR computer device is further programmed to receive the security vulnerability data at the VIR computer device in response to the query.

BACKGROUND OF THE INVENTION

The field of the present disclosure relates to enterprise computer security and, more particularly, to computer-based methods and systems for retrieving known software vulnerability profiles (also referred to as a “CVE”) from a central repository (e.g., database) of known vulnerabilities and identifying, based on the profiles, vulnerabilities that affect a plurality of computing assets.

A vulnerability is a flaw or weakness in a computer system's design, implementation, or operation and management that could be exploited to violate the system's security policy. Vulnerabilities are generally regarded as any aspect of a system or its components (e.g., computing asset) that allows a breach of security such as, but not limited to: executing commands as another user, accessing data contrary to access restrictions; posing as another entity; and conducting a denial of service attack. The impact of a security breach can be high. For example, a security breach can violate privacy laws and regulations that require organizations to secure private data stored within a computer system from release to unauthorized users.

One way to minimize the impact of vulnerabilities on a system is to perform periodic information technology security audits of the system and its components (e.g., computing assets). This systematic technical assessment measures a system's susceptibility to vulnerabilities. Audits can include interviewing staff, manually reviewing components for known vulnerabilities, reviewing application and operating system access controls, and analyzing physical access to the system. Systems can include computing assets such as personal computers, servers, mainframes, network routers, switches and other electronics which contain or facilitate the flow of data.

Known technology security audits utilize operators to evaluate the presence of vulnerabilities in software applications installed on computing assets in a computer system. The audits are performed on an application by application basis, comparing one or more lists of known vulnerabilities to a list of installed applications. These audits are time consuming and labor intensive, resulting in an audit frequency dictated by operator availability. Also, because conventional audits are performed manually, vulnerabilities discovered since the last update to the list of known vulnerabilities go undiscovered during the audit. Accordingly, the audits are time subjective. Additionally, upon discovery of a vulnerability, the operator must ascertain the resolution and apply it manually. Thus, known technology security audits fail to provide an accurate evaluation of known vulnerabilities in the installed application base of a computer system. Moreover, these known systems are unable to provide a real-time evaluation of vulnerabilities present in the computer system or its components.

Accordingly, it is desirable to evaluate technology assets for the presence of vulnerabilities in a rapid and accurate manner, and to provide vulnerability fixes to operators to speed the resolution of vulnerabilities.

DETAILED DESCRIPTION OF THE INVENTION

The methods and systems described herein relate to a vulnerability identification and resolution system that is configured to retrieve known software vulnerability profiles from a central repository (e.g., database) of known vulnerabilities and identify, based on the profiles, vulnerabilities that affect a plurality of computing assets.

In one example embodiment, a computer program is provided, and the program is embodied on a computer readable medium. In another example embodiment, the system is executed on a single computer system with a connection to a server computer. In a further example embodiment, the system is being run in a Windows® environment (Windows is a registered trademark of Microsoft Corporation, Redmond, Wash.). In yet another embodiment, the system is run on a mainframe environment and a UNIX® server environment (UNIX is a registered trademark of X/Open Company Limited located in Reading, Berkshire, United Kingdom). The application is flexible and designed to run in various different environments without compromising any major functionality. In some embodiments, the system includes multiple components distributed among a plurality of computing devices. One or more components may be in the form of computer-executable instructions embodied in a computer-readable medium. The systems and processes are not limited to the specific embodiments described herein. In addition, components of each system and each process can be practiced independent and separate from other components and processes described herein. Each component and process can also be used in combination with other assembly packages and processes.

The following detailed description illustrates embodiments of the invention by way of example and not by way of limitation. As used herein, an element or step recited in the singular and proceeded with the word “a” or “an” should be understood as not excluding plural elements or steps, unless such exclusion is explicitly recited. Furthermore, references to “example embodiment” or “one embodiment” of the present invention are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features.

The methods and systems described herein have a technical effect of facilitating communication between a vulnerability identification and resolution system executing on a first computer device and at least one database subsystem provided by a second computer device. Other technical effects, which are described herein, include vulnerability identification, vulnerability inventorying, and vulnerability resolution identification.

FIG. 1 is a simplified block diagram of an exemplary embodiment of a vulnerability identification and resolution system 100 including a vulnerability identification and resolution (VIR) computer device 121 in accordance with one embodiment of the present invention. In the example embodiment, computer system 100 is configured to compare one or more computing assets to a list of computing assets in a database containing vulnerabilities and vulnerability data associated with the computing assets. The computer system determines whether a computing asset of a computer system is affected by any vulnerability in the database and returns that information to the VIR computer device 121. The operator can then employ tools built into the VIR computer device 121 to access vulnerabilities and vulnerability data associated with the computer asset to administer a resolution (e.g., a fix or patch), making the asset no longer susceptible to a given vulnerability.

More specifically, in the exemplary embodiment, computer system 100 includes a server system 112, and a plurality of client sub-systems, also referred to as client systems 114, connected to server system 112. In one embodiment, client systems 114 are computers including a web browser, such that server system 112 is accessible to client systems 114 using the Internet. Client systems 114 are interconnected to the Internet through many interfaces including a network, such as a local area network (LAN) or a wide area network (WAN), dial-in-connections, cable modems, and special high-speed Integrated Services Digital Network (ISDN) lines. Client systems 114 could be any device capable of interconnecting to the Internet including a web-based phone, PDA, or other web-based connectable equipment. Server system 112 may be associated with any company having computer assets capable of being evaluated for vulnerabilities.

A database server 116 is connected to database 120, which contains information on a variety of matters, as described below in greater detail. In the exemplary embodiment, database 120 is a non-centralized database stored remotely from server system 112, and can be accessed by potential users at one of client systems 114 by logging onto server system 112 through one of client systems 114. Known vulnerabilities, discovered through many different channels, are tracked by a variety of publically accessible databases made available through the Internet. The database may be one of the Common Vulnerability and Exposure (CVE) database or the National Vulnerability Database (NVD). The Common Vulnerability and Exposure (CVE) database is a publicly available list of security vulnerability definitions maintained by MITRE Corporation. CVE is commercially available at http://cve.mitre.org. The National Vulnerability Database (NVD) is a comprehensive cyber security vulnerability database that integrates publicly available U.S. Government vulnerability resources and provides references to industry resources. NVD is a product of the National Institute of Science and Technology—Computer Security Division, is sponsored by the U.S. Department of Homeland Security—National Cyber Security Division, and is commercially available at http://nvd.nist.gov. CVE is a main repository of information relating to known vulnerabilities. CVE provides indexing and tracking of individual known vulnerabilities. NVD tracks descriptions of known vulnerabilities as well as their Common Vulnerability Scoring System (CVSS) ratings. CVSS ratings are based on a qualitative model of the impact of vulnerabilities. Two common uses of CVSS are prioritization of vulnerability remediation activities and in calculating the severity of vulnerabilities discovered in a computer system. NVD also contains information from the application vendor related to vulnerability manifestation and any fixes that have been created for removing the given vulnerability. In the example embodiment, database 120 may include any of these known vulnerabilities databases discussed herein.

In an alternate embodiment, database 120 may be a centralized database stored on server system 112 containing vulnerabilities as updated by an external source of known vulnerabilities.

System 100 also includes the VIR computer device 121, which may be connected to one or more client systems 114, and may be connected to server system 112. VIR computer device 121 can be interconnected to the Internet through various interfaces including a network, such as a LAN or a WAN, dial-in-connections, cable modems, wireless modems, and/or special high-speed ISDN lines. In one embodiment, VIR computer device 121 is located on server system 112 and can be accessed by potential users at one of client systems 114 by logging onto server system 112 through one of client systems 114. In an alternate embodiment, VIR computer device 121 may be non-centralized and is located remotely from server system 112.

In the example embodiment, each client system 114 is associated with a user and may be referred to as a user computer device 114. User computer device 114 may access and utilize VIR computer device 121 on server system 112. In one embodiment, user computer device 114 is a computer including a web browser, such that server system 112 is accessible to user computer device 114 using the Internet. User computer device 114 is interconnected to the Internet through many interfaces including a network, such as a local area network (LAN) or a wide area network (WAN), dial-in-connections, cable modems, and special high-speed ISDN lines. User computer device 114 may also include a remote computing device, such as a web-based phone, smartphone, mobile phone, personal digital assistant (PDA), iPhone® (iPhone is a registered trademark of Apple, Incorporated located in Cupertino, Calif.), Android® (Android is a registered trademark of Google Incorporated, located in Mountain View, Calif.), and/or any device capable of executing stored computer-readable instructions. User computer device 114 can be associated with a subject matter expert or with another user utilizing system 100. User computer device 114 is configured to access service applications offered by the company and communicate with other user computer devices 114 within system 100.

FIG. 2 is an expanded block diagram of a server architecture of a VIR system 122 including VIR computer device 121 (shown in FIG. 1) in accordance with one embodiment of the present invention. Components in system 122, identical to components of system 100 (shown in FIG. 1), are identified in FIG. 2 using the same reference numerals as used in FIG. 1.

The communication in the exemplary embodiment is illustrated as being performed using the Internet, however, any other wide area network (WAN) type communication can be utilized in other embodiments (e.g., the systems and processes are not limited to being practiced using the Internet). In addition, and rather than WAN 150, local area network 136 could be used in place of WAN 150.

In the exemplary embodiment, any authorized individual having a physical or virtualized workstation 154 can access system 122. At least one of the client systems includes a manager workstation 156 located at a remote location. Workstations 154 and 156 are personal computers or virtualized personal computers having a web browser. Also, workstations 154 and 156 are configured to communicate with server system 112. Furthermore, fax server 128 communicates with remotely located client systems, including a client system 156 using a telephone link. Fax server 128 is configured to communicate with other client systems 138, 140, and 142 as well.

User computer device 202 also includes an input device 220 for receiving input from user 201. Input device 220 may include, for example, a keyboard, a pointing device, a mouse, a stylus, a touch sensitive panel (e.g., a touch pad or a touch screen), a gyroscope, an accelerometer, a position detector, or an audio input device. A single component such as a touch screen may function as both an output device of media output component 215 and input device 220.

User computer device 202 may also include a communication interface 225, which can be communicatively coupled to a remote device such as server system 112. Communication interface 225 may include, for example, a wired or wireless network adapter or a wireless data transceiver for use with a mobile phone network (e.g., Global System for Mobile communications (GSM), 3G, 4G or Bluetooth) or other mobile data network (e.g., Worldwide Interoperability for Microwave Access (WIMAX)).

Stored in memory area 210 are, for example, computer readable instructions for providing a user interface to user 201 via media output component 215 and, optionally, receiving and processing input from input device 220. A user interface may include, among other possibilities, a web browser and client application. Web browsers enable users, such as user 201, to display and interact with media and other information typically embedded on a web page or a website from server system 112 (shown in FIGS. 1 and 2), including VIR computer device 121 (shown in FIGS. 1 and 2).

FIG. 5 is a data flow diagram 500 showing a process implemented by the VIR computer device 121 (shown in FIGS. 1 and 2) for identifying security vulnerabilities in a computer system in accordance with one embodiment of the present invention. In the example embodiment, VIR computer device 121 evaluates software applications. In alternate embodiments, VIR computer device 121 may evaluate any computer asset susceptible to a vulnerability. VIR computer device 121 utilizes a database 120 of known vulnerabilities to track and report on vulnerabilities that exist in computing assets of a computer system supported by a given organization. VIR computer device 121 is programmed to associate data obtained from an inventory application with publically available known vulnerability data. In the exemplary embodiment, VIR computer device 121 is programmed to utilize publically available known vulnerability data from databases maintained by the NIST as well as the CVE database. The VIR computer device 121 can be further programmed to retrieve vulnerability information from additional sources, and is not limited to the NIST databases and CVE database. The VIR computer device 121 is configured to compare a selected group of applications (or computing assets) with the data stored in the database 120. The VIR computer device 121 is programmed to track application versions that the given organization currently supports and indexes the application versions against the vulnerabilities that have been reported, providing a comprehensive listing of known vulnerabilities associated with each application version within the computer system. The database 120 can also include an inventory of each application (or computer asset) instance that exists in a computer system to be monitored. The VIR computer device 121 is written with an extensible framework that enables the use of a variety of inventory tools to be used with the device 121.

Referring to FIG. 5, during operation, an asset identifier is received 502 by the VIR computer device 121. The asset identifier can be a plurality of asset identifiers. The assets are computer assets, and are selected by a user, such as user 201. User 201 may also be referred to as analyst 201. VIR computer device 121 may display a list of asset identifiers identifying a plurality of computer assets on a display device, such as media output 215, for the analyst 201 to select from. The list is inclusive of all asset identifiers identifying all of the computing assets in the computer system. The VIR computer system 121 may then receive a plurality of asset identifiers identifying a plurality of computing assets selected for evaluation from an input device such as input 220.

Computer assets include computer software installed on server systems, personal computers and other computing devices, such as routers and gateways. Analyst 201 uses a computer device, such as user computer device 114 (shown in FIGS. 1 and 2), to interface with and operate VIR computer device 121. In the exemplary embodiment, VIR computer device 121 is stored on a server, for example, server 112 (shown in FIGS. 1 and 2).

For the specified computing asset or assets to be evaluated, VIR computer device 121 executes 504 a query on at least one database 120 storing security vulnerabilities. The query is designed to retrieve security vulnerability data associated with the computer asset or computer assets being evaluated. Security vulnerability data is queried for each of the selected plurality of assets. Security vulnerability data can include the following information relating to a given security vulnerability: a description of the security vulnerability, an evaluation of the severity of the vulnerability based on various metrics, the products affected by the vulnerability, external links related to the vulnerability such as links to a fix or patch, and other information useful in diagnosing and resolving vulnerabilities. In an alternative embodiment, the security vulnerability data can include any data that enables the VIR computer device 121 to operate as described herein.

After submission of the query to at least one database 120, VIR computer device 121 receives 506 security vulnerability data at the VIR computer device 121. The security vulnerability data may be referred to as “vulnerability data”. In the exemplary embodiment, VIR computer device 121 stores the vulnerability data in a database, such as database 120 (shown in FIG. 1), so that it can be accessed in the future for other analysis. The VIR computer system 121 can, according to the exemplary embodiment, generate a graphical representation illustrating the security vulnerability data of each computing asset of the selected plurality of computing assets relative to all other computing assets included within the selected plurality of computing assets. The VIR computing device 121 may also electronically display, on media output 215, the security vulnerability data for an analyst 201 to review.

Each computing asset on the media output 215 may be selected by analyst 201 to view detailed vulnerability data including a recommendation of a planned action to take for the computing asset to be resolved of the vulnerability. The VIR computer device 121 may also store in a memory device, such as memory 210, memory 310 or storage device 134, the security vulnerability data in order to parse the data and present the data for use to an analyst 201.

The VIR computer device 121 can, according to the exemplary embodiment, parse the security vulnerability data to extract an affected software identifier and a proposed resolution identifier, wherein the affected software identifier identifies a computing asset affected by a security vulnerability. The proposed resolution identifier identifies a proposed resolution to resolve the security vulnerability. The VIR computer device 121 can also update the query periodically, such as when one of the databases of security vulnerabilities is updated.

It is recognized that all of the actions programmed into the VIR computer device 121 can be executed by a computer-implemented method for evaluating a computer asset of an entity using a VIR computer device. It is also recognized that the actions programmed into the VIR computer device 121 can be executed by one or more non-transitory computer-readable storage media having computer-executable instructions embodied thereon for evaluating a computing asset of an entity using a VIR computer device.

FIG. 6 is a screenshot of a CVE listing screen 600 from VIR computer device 121 (shown in FIGS. 1 and 2) in accordance with an example embodiment of the present invention. CVE listing screen 600 may be accessed via a user computer, such as user computer device 114 (shown in FIGS. 1 and 2). In the example embodiment, CVE listing screen 600 includes a series of primary tabs 601, including a CVE list screen selection tab 602, a reports screen selection tab 604, a graphs screen selection tab 606, an update selection tab 608, an email selection tab 610, a help selection tab 612, and a break content selection tab 614. The primary tabs 601 do not change as an analyst 201 navigates through the application. Below these tabs appears a context menu 616 containing tabs specific to the primary tab 601 selected. The context menu 616 changes as the analyst 201 navigates through the application. For the primary tab CVE List 602, the context menu 616 contains a display tab 618, a CVE information tab 620, a reanalyze tab 622, and a modify tab 624.

The CVE listing screen 600 is used to display a list of the vulnerabilities that the VIR computer device 121 has determined are applicable to the current computer assets in the computer system. In the exemplary embodiment, five applications 626 (e.g., computer assets) have been used by the VIR computer device 121 to ascertain relevant vulnerabilities: Apache (a product of the Apache Software Foundation), JBoss (a product of Red Hat, Inc.), Apache Tomcat (a product of the Apache Software Foundation), WebSEAL (a product of IBM, Inc.) and WebSphere® (a registered trademark and product of IBM, Inc.). From this CVE listing screen 600, the analyst 201 can see that Apache has six versions with vulnerabilities in the computer system.
